the config file is copied to the no need host

[Jeffrey Zhang]

The service config file is copy to the all the related host, which is no need.
For example, in the cinder case,
the cinder-backup is part of storage host, but it will also be created on the controller host

this should be improved. Only copy the config file when the host is *really* need.
